Of course renting sucks if you sell a house for $2M and rent something worth much less. $2,800 a month gets you a about a 650k valued house. You are not comparing apples to apples.
I am in a decked out property worth about 1.5M and my rent is 3,500 a month. I am renting for about 1/3 of the total carrying costs of owning.
I have no complaints… renting has been very good to me.
